192+N		07:00		Intercalibration 2	CDS/SEM/EIT/SUMER/UVCS

(cycle falls to once every 4 weeks when agreed)

* = These "pre-L1" intercalibration activities will be supported by instruments
as they become available.

CDS/SUMER JOPS:

DAY SINCE	GSFC TIME   JOP				INVOLVES
LAUNCH
125+N		07:00	SUMER/CDS/EIT/MDI ALIGN CAL	CDS/SUMER/EIT/MDI
126+N		07:00	SUMER/CDS INTENS CROSS CAL	CDS/SUMER
153+N		07:00	SUMER/CDS/EIT/MDI ALIGN CAL	CDS/SUMER/EIT/MDI

182+N		07:00	SUMER/CDS INTENS CROSS CAL	CDS/SUMER


ESTIMATED DURATIONS:

INTERCALIBRATION 1 - 150-200 minutes (depending on instrument)
INTERCALIBRATION 2 - 140-160 minutes (depending on instrument)
SUMER/CDS/EIT ALIGN - 160-175 minutes (depending etc...)
SUMER/CDS INT CROSS-CAL - 94-112 minutes (depending etc...)


Clearly there can be some flexibility. However, we have always listed the EIT high
telemetry period as 06:30 to 07:00 and, rather than leave an awkward hour before
the JOP start, I have listed them from 07:00.

All of the times are Goddard time!!!!!!!
